/*! \brief a speed optimized plotter class
\ingroup jkqtfastplotter
This plotter class is (in contrast to JKQTPlotter) optimized for speed. It allows to plot function graphs/data in
a simple manner. The focus of design was not on a nice output (athough this is not unimportant), but on the speed
of the output. So the class may be used to di quick plotting of data, i.e. in fast image sequence applications.
These measures were taken to increase speed:
- The coordinate system is drawn onto an internal image which is only updated, when the size of the widget
or a property of the coordinate system changes. When only the data changes, just the data plot has to be
updated.
- The class uses an internal buffer with the complete image, so a repaint does not always trigger a complete
repaint of all elements, but just measns painting the internal image to the screen. This also allows to
plot selections ... over the plot, without having to replot the plots.
- The definition of the coordinate system as well as the definition the system ticks ... is reduced to the absolute
minimum.
- The method setPlotUpdateEnabled() allows to prevent replotting of the class contents, e.g. when you want to set
a multitude of parameters without triggering a replot every time.
.
The class supports these features:
- coordinate axes may be linear or logarithmic.
- ticks and tick labels are drawn by a simple algorithm: The user has to supply two values:
\c zeroTick is a tick value that exists in any case (i.e. 0) and \c tickDistance which contains the distance
between two ticks (only applicable to linear axes). Then the class starts to draw at zeroTick and move on to
\c zeroTick+tickDistance and \c zeroTick-tickDistance until \c min / \c max of the axis is reached. For logarithmic axes
the class uses \c zeroTick*10 and \c zeroTick/10
- plot may contain a grid (x and y grid may be switched on/off separately).
- plots are represented by descendents of JKQTFPPlot and the plotting code is completely
contained therein (and should be speed optimized).
- it is possible to keep a specified aspect ratio
- it is possible to couple different plots in a way, that they are plottetd with the same width/height
both in pixel and world coordinates by using plotterSizesChanged() and synchronizeX() / synchronizeY().
